Through my doctoral and postdoctoral education I received training in the areas of developmental psychology, poverty, and public policy. My research has focused on 1. family-related factors, such as poverty and family structure, and their influence food insecurity and food assistance program participation and 2. how family-related factors and participation in public assistance programs influence child and adult health outcomes. As a NICHD K12 Scholar in the Building Interdisciplinary Careers in Women’s Health (BIRCWH) Program, I focused on the how individual-level contextual factors and policies predict gender differences in obesity. In the future, I plan on continue the above lines of research by including measures of the built environment, nutrition, and physical activity.
